Airbus Defence & Space Les Mureaux

Created by Airbus Group and Safran, Airbus Safran Launchers is a 50/50 joint venture bringing together the expertise and assets of both groups in terms of civil and military space launchers.
Its industrial and technological heritage, linked to the passion which drives the men and women of Airbus Safran Launchers, is what has enabled it to become the current world leader in space access.
Through clever operations at all levels, Airbus Safran Launchers offers innovative and competitive solutions to its customers, in order to bring the European space industry to its highest level and thereby guarantee independent access to space.

Airbus Group is a global leader in aeronautics, space and related services. In 2015, the Group - comprising Airbus, Airbus Defence and Space and Airbus Helicopters - generated revenues of € 64.5 billion and employed a workforce of around 136,600.

Our people work with passion and determination to make the world a more connected, safer and smarter place. Taking pride in our work, we draw on each other's expertise and experience to achieve excellence. Our diversity and teamwork culture propel us to accomplish the extraordinary - on the ground, in the sky and in space.

Description of the job

Airbus Safran Launchers (Les Mureaux) is looking for an intern for a 6-month internship.

Airbus Safran Launchers on the one hand possesses a CFD (Computational Fluid Dynamics) code, and also a specific code for calculating flow radiation (gases and particles) and the radiation of structures (solid walls).
The objective aimed at is to couple these 2 software packages in order to be able to process multi-physics cases, where the radiation is considered as an energy source in the CFD code.

This internship will start on 2nd January 2017 (subject to some flexibility).

Tasks & accountabilities

Your main tasks will include:
1/ A first stage will be to analyse the solvers and methods associated with each code:

·  CFD: code of multiple types (gases), multi-phases (solid particles and liquids), turbulent, reactive, unsteady.
·  Radiation: code based on the ray launcher technique modelling the thermal radiation of structures, the radiation of gases (band model), the emission and diffusion of radiation by particles.

You will learn how to use these two codes separately, but for a common application, for example a 2-phase flow in a confined space with solid radiating walls.
By varying the parameters, it will be possible to evaluate the significance of the various contributors in the energy balance (thermal and radiation).

2/ In a second stage, based on these facts, you will analyse the possibilities of different coupling methods: how to take into account a radiation source term in the CFD software, how to take into account the production of radiation in each flow cell in order to calculate the radiation transfer in different directions.
In addition to architecture and model considerations, you will consider aspects such as calculation time, memory size, programming methods (parallelisation for example). This methods analysis will lead to the adoption of one or more solutions, with an associated work plan.
Finally, the impact on the software of the adopted solution will be detailed:

·  Interface to be constructed for the 2 codes,
·  Supplementary programming in the CFD code,
·  Update of the programming structure of the radiation code.

Initial developments associated with simple applications may be undertaken.
